(Ground Water Level Recorder)


Ground water is among the Nation’s most precious natural resources. Measurements of water levels in
wells provide the most fundamental indicator of the status of this resource and are critical to meaningful
evaluations of the quantity and quality of ground water and its interaction with surface water. Next Sense
Technologies made GWLR-AT-01, Digital Ground Water Level Recorder Piezometer, is a data logger and
submersible pressure transducer combination designed for remote monitoring and recording of water
level or pore pressure data. The sensor is lowered into the well on a reinforced cable and submerged
below the water. Once in place, the initial water pressure reading is synced with the current water level.
The unit then monitors the water pressure for changes, and the pressure difference is converted to a
change in water level. The entire unit is hermetically sealed to prevent any moisture from getting into the
instruments circuitry.
